PUMP AS-LIFT 6I0571 - Caterpillar

Coolant System
Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure.
To relieve the pressure from the coolant system, turn off the machine. Allow the cooling system pressure cap to cool. Remove the cooling system pressure cap slowly to relieve pressure.Fuel System
To relieve the pressure from the fuel system, turn off the machine.Hydraulic System
Personal injury can result from hydraulic oil pressure and hot oil.Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.
Fan/Brake Circuit
To relieve the pressure from the fan/brake circuit, turn off the machine. Apply the service brake pedal to the floor for one second and release the pedal completely for 9 seconds, for a minimum of 15 applications. Do not assume that all the pressure is removed from the circuit because the brake pedal does not have resistance. Remove the pressure when you work on any part of the fan/brake circuit.Steering Circuit
To relieve the pressure from the steering circuit, turn off the machine. The steering valve has enough leakage to allow for oil to return to the tank. Wait 10 minutes before you open the steering system. This step will allow any residual pressure to drain into the tank.Implement Circuit
Illustration 1 g01423186Blade Lift, Plow Lift, and Wing Lift with Float
Push the right-hand joystick to the most forward DETENT position and push the left-hand joystick to the most forward DETENT position. When you release either joystick, the joysticks will return to the HOLD position. The right side of the blade will remain in the FLOAT position until the joystick is moved forward or rearward. The left side of the blade will remain in the FLOAT position until the joystick is moved forward or rearward. The lock valves (3), (25), (27), and (19) will be forced open and the pressurized oil will return to the hydraulic tank. Rest the blade on the ground in the FLOAT position for 30 seconds. Turn the machine to the OFF position. Wait at least 10 minutes before you open the blade lift relief lines (26) and (28) if the machine is equipped with the blade cushion accumulators. If the machine cannot be started or the blade float is not working properly, refer to Operation and Maintenance Manual, "System Pressure Release - Side Shift, Blade Tip" for the blade lift circuit. If the machine cannot be started or the blade float is not working properly, refer to Operation and Maintenance Manual, "System Pressure Release - Wing Lift and Wing Tilt without Float" for the wing tilt circuit.Wheel Lean, Circle Drive, Center Shift, and
